Band Protocol is a cross-chain data oracle platform that aims to connect real-world data and APIs to smart contracts. It intends to facilitate the exchange of information between on-chain and off-chain data sources, thereby unlocking a myriad of new use cases for developers. Band Protocol can incorporate any type of real-world data into decentralized application logic, including sports, weather, random numbers, price feed data, and more. The native token of the Band Protocol ecosystem, BAND, is used as collateral by validators involved in fulfilling data requests and as the main medium of exchange on BandChain.

Band Protocol operates by supplying reputable, verifiable real-world data to blockchains. It initially launched as an ERC-20 project on the Ethereum blockchain in September 2019, but transitioned to the Cosmos network with the release of Band Protocol 2.0. The new protocol is built on BandChain using the Cosmos SDK. Oracle nodes on BandChain not only relay data but are also involved in block production/validation, giving them a dual role. Band Protocol aims to leverage Cosmos' still in-development Inter Blockchain Communication (IBC) protocol to achieve its cross-chain data transfer.

Band Protocol aims to unlock a range of new use cases for developers to explore. Developers can use any type of real-world data as part of their decentralized application logic, including sports, weather, random numbers, price feed data, and more. This flexibility allows for the creation of custom-made oracles using WebAssembly to connect smart contracts with traditional web APIs within minutes. Band Protocol's oracle design also allows anyone to start servicing data requests, offering extremely simple smart contract integration.

Band Protocol was founded in 2017 by Soravis Srinawakoon, Paul Chonpimai, and Sorawit Suriyakarn. The platform is supported by major global investors, including Sequoia Capital, Dunamu & Partners, and Spartan Group. The Band Protocol LinkedIn page currently lists a total of 20 additional employees, most of whom are scattered throughout Asia, and include designers, developers, and engineers.

The BAND token plays an integral role in the Band Protocol ecosystem. It has several key utilities, including allocating tokens, accessing data, and making network participation contributions. BAND token holders can allocate their tokens to participate in the governance of the Band Protocol, voting on protocol upgrades, changes, and proposals. This aims to keep the platform transparent, accountable, and responsive to the needs of its users. BAND token holders can also use their tokens to access specific data feeds on the Band Protocol, allowing developers to design custom data oracles for their specific needs and requirements. Additionally, BAND tokens are used for network participation contributions on the Band Protocol. These contributions encourage validators to process transactions and uphold the network's integrity. The BAND token contributes to the token's deflationary model, with a portion of network participation contributions removed after each transaction.

Band Protocol aims to ensure the accuracy and reliability of data provided by oracles through a decentralized network of validators. These validators are tasked with retrieving and verifying real-time data from various sources. The data provided by these validators is then aggregated using Band Protocol's consensus mechanism to produce a final data point. Validators are encouraged to provide accurate data with the potential risk of losing their staked BAND tokens if they provide inaccurate data. This system of checks and balances strives to ensure the integrity and reliability of the data provided by Band Protocol's oracles. Band Protocol's use of blockchain technology seeks to provide transparency and immutability, further aiming to strengthen its reliability as an oracle solution.

Band Protocol seeks to provide a source of data that is as reliable as possible for Decentralized Finance (DeFi) applications, smart contracts, and decentralized applications (dApps). The types of data that can be accessed through Band Protocol oracles range from current events and sports results to weather forecasts and even random numbers. This data is crucial for the functioning of many blockchain-based applications. Band Protocol aims to focus on aspects such as speed, scalability, cross-chain compatibility, and data flexibility, and seeks to offer data that is as accurate and timely as possible to a wide variety of public blockchains.

The process of engaging and choosing data providers in Band Protocol is facilitated by its native token, BAND. Network participants who hold BAND tokens undertake the process of verifying data via consensus. These participants fall into two categories: validators and delegators. Validators aim to participate in the creation of new blocks and contribute to Band Protocol’s Delegated Proof-of-Stake (DPoS) consensus protocol by voting on the authenticity of data. For their efforts, validators receive non-financial incentives. When a smart contract requests data through the Band Protocol oracle system, randomly chosen validators retrieve the requested information and submit the data in a report to the BandChain. The individual reports from validators are then aggregated into a unified final result, which is permanently stored on Band Protocol and becomes available for the requesting smart contract. The Band Protocol network uses its native BAND token to encourage validators to participate in the creation of new blocks, contribute to consensus, and address data requests.

Band Protocol's decentralized approach aims to prevent any single entity from controlling the data being fed to smart contracts, thereby striving to reduce the risk of manipulation. Band Protocol uses a consensus mechanism to determine the accuracy of the data they provide. This involves multiple nodes independently retrieving and validating the same data from external sources. Once a consensus is reached among the nodes, the data is considered reliable and is passed on to the smart contracts. To encourage node operators to participate honestly and provide accurate data, Band Protocol implements incentive structures. Nodes that provide accurate data receive non-monetary incentives, while those found to be malicious or inaccurate may face penalties or risk losing their staked tokens.

Band Protocol oracles can be integrated into a variety of applications and projects that require consistent, timely, and decentralized data. These include Decentralized Finance (DeFi) applications, which depend on accurate financial data for smart contract computations. Examples of DeFi use-cases include markets for resource allocation and utilization, algorithmic stablecoins, futures and perpetuals, synthetic assets, financial insurance, and asset management. Band Protocol oracles also support financial prediction markets, proof-of-custody oracles for cross-chain DeFi applications, peer-to-peer trading platforms, decentralized asset bridges, options contracts, and programmable & conditional transactions. Band Protocol oracles have potential applications in projects that require data from external APIs or traditional web services, and can be integrated into a variety of professional and institutional applications.

Band Protocol's dispute resolution mechanism for oracle data is centered around its distinct validation process and the role of validators within its network. Validators are tasked with supplying accurate data to the network and commit the native cryptocurrency of the protocol as collateral. If they supply inaccurate data, they risk losing their committed tokens. When a smart contract requires data, it sends a data request to the Band Protocol network. Validators participate in providing the requested data, motivated by the potential to receive non-monetary rewards in the form of the protocol's native tokens. After the data is submitted, Band Protocol employs a consensus mechanism to aggregate the data and produce a final data point. This consensus mechanism is designed to deter malicious validators from manipulating or compromising the data. The validator's committed tokens act as a deterrent, and if a validator is found to have supplied inaccurate data, their committed tokens are forfeited.

A key strategy is the Band Protocol Grants Program, which aims to support projects that contribute to the growth and advancement of decentralized applications and Web3. The program is structured to assist projects in four main categories: Core Infrastructure Grants, Application Development Grants, Community Initiatives Grants, and Research Grants. The intention is to stimulate the development of new use cases and broaden the influence of decentralized applications. It also aims to facilitate the adoption of blockchain technology. Band Protocol also encourages community participation through its decentralized governance model. In this model, BAND token holders have the ability to propose and vote on changes to the protocol. Band Protocol also organizes activities such as educational sessions and development workshops to foster community growth, education, and awareness.
